Hi Ryze,

I'm now living in the UK, but originally from Ottawa. We got here 2 months ago so the information I have is up to date.

House rental: this is a bit tricky as it varies greatly depending on the area, size and quality of the house. Realistically, you should expect to pay between 1400$ to 1800$ a month. You could find cheaper or more expensive, it'll all depends on what's on the market when you are ready to move.
Furnitures: Most of apartments/houses for rent will include a fridge/freezer, cooker, dishwasher and washer and dryer. Their is an IKEA store in Ottawa so you might want to have a look at their website for some furnitures. Sears.ca also have some great deals. An other option would be to check the kijiji.ca website for used furnitures. Once again, it all depends on what you're looking for, but you should be able to buy a dinning room set, a couch, 3 beds (1 queen and 2 single) for about 3000$ new.
Utilities
Cable tv: 50$
Internet: 50$
Phone line: 40$
Car (intermediate, used): 6000$ (you could get a 2002 Toyota Corolla or Honda Civic for exemple)
Fuel: around 1.20$/ litter. So probably around 50$/week
Parking: Depends where you work. Some offices have free parking. If not, probably around 80$/month.
Kids schooling(public elementary Y1 & Y2): Free excepts for the books and furnitures, around 200$/year
Groceries n marketting (2 adults, 2 kids): Groceries, around 400$/monthly, miscellenious: well, it all depends on what you need. I'd say around 200$ to 300$.
Other items (clothes, medicine): Maybe your company has a medical insurance and that should cover most of the cost of medicine (prescription).
For the stuff that is sold off the counter you should expect to pay between 30 and 50$ monthly (ie: cold medicine, anti acid, pain killer)
Kid clothes average price: Jacket 50$, pants 20$, sweater 25$
Adults: Jacket 100$, pants 60$, sweater 75$
I'm sure you could find cheaper then that, but I wanted to give you an idea of what it costs in the boutiques.
For the insurances, you should expect to pay around 100$/month for the car and around 50$ for contents. It could be higher if the rent doesn't include the building coverage.

Hope that's help.

Cheers,

Cindy
